REVERSIBLE WINDOW SASH.

Application led August 1, 1922y Serial No. 579,059.

To all whom t may conc-em:

Be it known that I, DnNIsoN MANNING, a citizen of the United States of America. residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Reversible Window Sashes, of which the following is a speciiication.

My inventionrelates to a window sas adapted to be reversed to facilitate the cleaning of the glass on bothsides from within the house.

More particularly the object of my invention is to provide a window sash which will have the same appearance as the present standard sash, which willbe free to slide yin the frame, and which will yet have the glass carried in an inner sash which can be lowered and reversed without disconnection from the outer sash.

A further feature of my invention consists in providing means to pivotally suspend the inner sash, when lowered, from its respective outer sash, the sashes being designed and arranged so that the pivotally suspended inner sash is free to swing about a vertical axis and toclear not onlythe outer sash but all the other window parts.

My invention also comprises the novel details of construction and arrangements of parts, which are hereinafter .more particularly described, reference being had to the accompanying drawings which form a part of this specification.. and in which Fig. 1 is a vertical cross-sectional view through the center of a window frame showing the lower sash raised and its respective swinging sash in lower position from rits' pivot.

Fig. 2 is a perspective view of the lower sash as shown in Fig. 1, dotted lines showing the inner sash being swung on its pivot.

Fig. 3 is a partial sectional view taken on the line 3-*3 of Fig. 4.

Fig. 4 is a longitudinal sectional view taken on the line 4 4 ofFig. 3.

Fig. 5 is an enlarged longitudinal sectional view of the central portion of the sash taken along the line 5-5 of Fig. 6.

Fig. 6 is a vertical sectionalgview taken on the line 6-6 of Fig. 5, showing the botf tom rail of the pivoted sash assembled between the bottom cross rails of the outer sash. Y

Fig. 7 is a detail View showing the sash pivot resting on the bottom rails of the outerv sash. y

F i g. 8 is a plan view of a modified form of the sash having a top cross bar carrying its pivot and used in lieu of the bottom cross bars on the outer sash.

Fig. 9 is a sectional view taken on the line 9 9 of Fig. 8. y

Similar reference numerals refer to similar parts throughout the drawings.

I show my invention associatedV with a window frame 1 having a bottom ledge 2 and the usual vertical way strips 3 between which the upper and lower sashes are adapted to slide. My improved sash is adapted to slide up and down in the window frame just as is at present customary, and each of the sashes is provided with the usual sash cords 4 connectedto sash weights by which it is suspended. I have illustrated myv invention in detail more particularly as applied to the lower sash but the principles of conltruction are the same for the upper sas Referring now to Fig. 2, which shows the lowerv sash in detail, the same comprises an outer sash having sides 5, a top 6 and a pair of spaced bottom rails 7 connecting the sides and disposed at the front and rear of the vertical grooves 8 provided in the inner faces of the sides. These grooves 8, asl shown more clearly in Figs. 3 and 4, form slideways which are adapted to receive the innersash comprising a top rail 9, side rails 10, and a bottom rail 11, either connected to or formed integral with a bottom bar 12, which extends on each side beyond the sides 10 and is adapted, when raised, to bereceived in and to close the space formed between the bottom shoulders 13 on the outer s sash sides 5 which, it will be noted, are offset from the grooves 8. The bottom rail 11 is adapted to t snugly between they bottom rails 7 of thevouter sash, as is shown more clearly in Fig. 6. In the inner sash I mount the glass 14 in the manner well understood in the art and at the center of the top rail 9 I attach a bracket 15 carrying a vertical pivot stud 16 having an enlarged bevelled head 17 thereon. This head is adapted to be received in an 'enlarged circular socket formed in the under side of the upper rail 6 of the outer sash, which rail also has a transverse groove or channel 19 which receives the upper rail 9 of the inner sash to 6 carries give a weather tight joint, This upper rail a bevelle'd latch .pin 220 having 'a grip 21 exposed onthe inner side of the sash and` engaged by a, flat spring 22, also at'- tached to the rail G andnormally 'pressing the latch into the opening 18 where it is adapted to engage under the button head 17 and support the low-er sash in raised position, as shown in the upper sash'in Fig. 1. The button head is larger ythan the space between the bottom rails 7 of the outer sash but is small enoughfto .pass up through the notchesfZ .provided at one sid'ejin said rails 7, (see Fig. 2'). The length of the shank 1G is greater than the depth of the rails 7, as seen in Fig. 7, and thus when the innersash is lowered, after 'releasing the -latch 20, its button will engagethe rails 7 and thus pivotally support. the lower sash with its upper rail i9 slightly below the level of the rails 7 and clear of the grooves 8 and spaced from the shoulders 18.' It will be observed, .by reference to Fig. 4, that the inner wall of each slideway 8 is sutiicie'ntly spaced from the inner wall of the adjacent shoulder 13 to leave an vample clearance for vthe side rails 10 of `the inner sash, in swinging about itsY vertical center, to clear these shoulders 13.

In Figs. 8 and 9 Iliave shown a modification in which the bottom rails 7 of the outer sash are omitted and I provide along the inner wall of each slidewa-y groove 8 a groove 24 which stops just short of the lower end -ofthe slideway, thereby leaving a stop shoulder 25. To the center of the top rail 9 of the inner sash I pivot by means of a pin 26a cross bar27 havingits ends 28 reduced and A'adapted to overhang the side edges of the inner sash and to travel in the grooves 24. It follows that this bar 27 will be arrested by the shoulders 25 when the inner sash has been fully lowered and will pivotally support 'the latter with its top rail9 clear to swing about its vertical aXis and thus present both sides of the glass to be cleaned. The cross bar 27 is undercut below its ends 28 and is designed so that by cocking the lower sash this ybar can be disengaged from the slideway grooves 8 and the inner sash entirely removed if desired.: Any suitable latch means may be provided to hold lthe inner sash in raised position.

In operation, 4referring to Figs. 1 to 7, the outer sash Vis mounted to slide in the sash frame :guides in the customary manner. The inner'sash, disposedat an angle tothe outer sash,is shifted into position so thatits pivot pin 17 can Abef inserted upwardly throu'ghthe notehedportions 23 ofthe outer sash rails 7 antlythenshifted'to central position, Aafter which by turning'the inner sash parallel withrithe outer sash, the :inner sash 'can be run fu-pfinto' theslid'ewa'y grooves 8 and its pivot "pin fhead i17- Aengaged `byj'the vlatch 20" which will thus hold4 the sashes assembled in operating osition. In this position, the assembled sas i presents no appreciable dit# ference in appearance from the ordinary sash and all joints are of such character as to prevent any appreciable air leakage.

In cleaning the window the inner side of thegl'a'ss; is first cleaned as usual, then the sash is lowered, the latch is released and the weights hit the outer sash to its uppermost`V can be again reversed wood or metal, or wood and metalland that Y any suitable arrangement of `both latch 'and pivot can be substituted.

i Though I have described with great ,par-l ticularity the vvdetails of the embodiment of the invention herein shown, it is not yto be construed that I fam limited thereto as changes in arrangement and substitution of equivalents may be made by those skilled in the art vwithout departing fromthe invention as deiined in the appended claims.

Having .thus .described my invention, what Iclaim as new and desire to secure by Letters Patent, Eis Y 1 1.
